tween the large macrochaetse ; six scutellar bristles, the 
median ones much further from one another than the 
others so that there is a group of three on each side, the 
middle one of which is much longer than either the lateral 
or median one. Propleura sparsely hairy, with four small 
bristles at the base of the coxa and a large, erect one at 
the upper angle; mesopleura sparsely hairy on the upper 
half. Front tibia with a series of four moderately long 
bristles on the outer (extensor) edge, one at the basal 
third, one at middle and two between middle and apex. 
Middle tibia with a pair of long bristles near base (Fig. 1, 
c) and two short ones externally at tip. Hind tibia with- 
out long bristles. Abdomen very weakly chitinized; with 
a distinct large dorsal plate on the second and a small trans- 
verse plate on the second segment. Wings rather small, 
costa extending beyond the middle (Fig. 1, b), its cilia 
very long ; third vein forked well before apex ; base of third 
vein with one very long bristle near base ; seventh vein not 
distinct. 
Described from three specimens taken by Dr. J. W. 
Chapman with rEnictus martini Forel, at his summer camp 
in the mountains near Dumaguete, Negros Oriental, Phi- 
lippine Islands. Dr. Chapman tells me that the Phorids 
ran along in the foray during the migration of the colony, 
making faster progress than the ants.
